Firoiu Dan Nicolae and the Glowing Series.
The artist
Firoiu Dan Nicolae
Artist, producer and curator
The founder of Coco Agency. He began in music: as the psytrance act Whicked Hayo, as manager of Juno Reactor, and for a decade as festival director of Rhakti Dei and Tribes Gathering in Belgium.
He then turned to exhibitions, creating and touring shows such as Dino Planet, Living Dragons and Giant Bugs, and curating Living Dinosaurs, seen by more than 12 million visitors. The Glowing Series brings that sense of spectacle to the page. He lives in Sofia.

From the stage to the page
Firoiu Dan Nicolae is an artist, producer and curator, the founder of Coco Agency, and the author and artist of the Glowing Series. He lives and works in Sofia.
He began in music. He performed as the psytrance act Whicked Hayo, worked as manager of Juno Reactor, and for a decade was festival director of Rhakti Dei and Tribes Gathering in Belgium. Festivals taught him how light, sound and a crowd can turn a field into another world for a night, and that sense of spectacle has stayed with him in everything he has made since.
He then turned to exhibitions. As founder of Coco Agency, he has created and toured shows such as Dino Planet, Living Dragons, Giant Bugs and Glowing Garden, and he curated Living Dinosaurs. Together they have been seen by more than twelve million visitors. He has made exhibitions for more than ten years, and the habits of that work run through the books: thinking about how a visitor walks through a room, what they see first, and what makes a family stop and look.
An art style of his own
His art style is recognisable at a glance. Each creature appears as living glass, lit from within, its inner structure of bone, muscle and nerve glowing through in neon colour against pure black. In the deep sea, where animals make their own light, the style found its natural subject in Glowing Oceans. Among insects and spiders, in Glowing Bugs, it turned the smallest animals into jewels. With the dinosaurs, it does something different: it takes animals known only from stone and gives them back a body.
The epigraph he wrote for the book says it in one line: Where others see a fossil, I see a spectrum.
Spectacle with care
The Glowing Series pairs that spectacle with care. The plates are free; the facts are not. For each book he has worked with sources from the start, tracing every statement to a paper, a museum or a book, and planning a specialist reading before print. The aim is a book that a child opens for the pictures and an adult trusts for the text.
The Glowing Series
Glowing Dinosaurs is volume IV of the series. It follows Glowing Oceans, the creatures of the deep sea that make their own light; Glowing Bugs, insects, spiders and other small creatures as living glass; and Most Dangerous Bugs, its companion. Glowing Dinosaurs has its own companion, Most Dangerous Dinosaurs. Each atlas can also become an exhibition, so a venue that shows one series one year can show another the next, each with its own book.
For the book, the exhibitions, the animatronics or a conversation about working together, write to him at Coco Agency.
The Glowing Series

Most Dangerous Dinosaurs
Its companion: 24 animals and their weapons.
Why glowing animals
The Glowing Series began with a simple idea: to draw living things as if light came from inside them, so that bone, muscle and form could be seen at a glance. In Glowing Oceans the subject was the deep-sea creatures that really do make their own light. In Glowing Dinosaurs the light is an invention, a way of bringing animals known only from stone back to life, while every fact beside the pictures stays true to the science.

How we handle your personal data
Last updated 28 October 2026
Who is responsible
The controller of your personal data is CocoAgency EOOD (Coco Agency), represented by Firoiu Dan Nicolae, Lavele 18A, apt. 8, Sofia, Bulgaria, company number (EIK) 202075523, VAT number BG202075523. You can reach us at dan@cocoagency.bg or +359 87 612 8527.
What this website does not do
This website has no user accounts, no forms that store your data, no advertising, no analytics and no tracking cookies. We do not sell or rent personal data to anyone.
What we collect, and why
When you write to us. The buttons “Reserve a copy”, “Ask for trade terms”, “Ask for dates”, “Enquire privately” and similar open your own email program. When you send that email we receive your email address, your name if you give it, and whatever you write. We use it only to answer you and to deal with your request: a reservation, a trade, rights or exhibition enquiry, or a question.
Legal bases. For reservations, trade, publishing and exhibition enquiries: steps taken at your request before a possible contract (Article 6(1)(b) GDPR). For other messages: our legitimate interest in answering people who contact us (Article 6(1)(f)). Where we must keep records by law, such as invoices: a legal obligation (Article 6(1)(c)).
Settings on your own device. If you switch on the jungle sound, the website remembers that choice in your browser’s local storage, on your device only. It is not sent to us and is not used to identify you. You can clear it at any time in your browser settings.
Technical data. To show the page, your browser connects to our hosting provider, which necessarily receives technical data such as your IP address and browser type, and keeps it in short-lived server logs for security. The typefaces are served from this website itself; no data is sent to Google or any other font service.
Who else receives your data
Only the providers we need: our email provider and the hosting provider described above, and, if you go on to order or work with us, our accountants, couriers or printers as needed for that order. Some of these providers may process data outside the European Economic Area; where they do, the transfer relies on the safeguards they offer, such as the European Commission’s standard contractual clauses or the EU-US Data Privacy Framework.
How long we keep it
Emails are kept for as long as needed to deal with your request and then for up to 24 months after our last contact, so that we can follow up on the same matter. If a contract follows, records are kept for as long as Bulgarian law requires, for example accounting records. Reservations that do not lead to an order are deleted once the book is released or when you ask us.
Your rights
You can ask us at any time to access your data, correct it, delete it, restrict or object to its use, or receive it in a portable format. Where we rely on your consent, you can withdraw it at any time. Write to dan@cocoagency.bg; we answer within one month.
You also have the right to complain to the Bulgarian supervisory authority, the Commission for Personal Data Protection (www.cpdp.bg), or to the authority in the EU country where you live.
Children
The book is made for families, but this website does not knowingly collect data from children. If you are under 14, please ask a parent or guardian to write to us for you.
Changes
We may update this policy when the website or the law changes. The date at the top shows the latest version.
